A colleague of mine is about to start work on a Wild West film. For one of the props he bought this water bottle, a classic western trope:
I used the following weathering powders available from Forge World:
I then ‘fixed’ the weathering powders with some white spirit. Now, this is a bit of a misnomer as it doesn’t completely prevent them from coming up, but it does improve the consistency. Just place a brush loaded with white spirit next to the powders and the liquid will run into them. Then leave it to dry.
Once dry I repeated the process with a little medium earth. I used less than with the rust, just to provide some contrast. Then the third step was a little dark Iron to break up the metal parts.
Have a look at the finished piece:
